Race enthusiast: your day is coming! The 4th annual race offers a flat, fast course with scenic views through all 3 counties in the Great Lakes Bay Region. Starting in Midland, the course again stretches across Bay and Saginaw counties before the epic finish in Dow Diamond. Proceeds from your race entry fee go directly to the development and maintenance of the Great Lakes Bay Regional Trails which are included in both the marathon and ½ marathon courses. Join us for your first race, your 51st or bring a team and compete in the marathon relay, as we run for fun, run for health and run for the trails. Part of the Dow Weekend of Races.
